Pattison Ave.

The Sixers have been dealt another blow on the injury front as guard Jason Richardson is scheduled to have season-ending knee surgery next week, according to Marc J. Spears of Yahoo! Sports.

The recovery time from his surgery is expected to be six to nine months.

Richardson had his knee drained back on Jan. 17 and played the next night during an overtime win over the Raptors. He has not played since.

In 33 games this season, the 32-year-old averaged 10.5 points per game, 3.8 rebounds while playing just under 13 minutes per outing.

Richardson possibly being done for the season makes both pieces to the Sixers’ offseason trade sidelined with injuries. The team has been dealing with the day-to-day drama of the trade’s biggest piece, Andrew Bynum, for the entire season.

The Sixers were already dealing with bad news this week after losing forward Thaddeus Young for three weeks due to a strained left hamstring.

UPDATE: The Sixers have released a statement via the team's Twitter account saying that no decision has been made on surgery just yet for Richardson.

In the statement, the Sixers said that they are scheduling an appointment for Richardson to get another opinion on his knee as early as Thursday. As of right now, according to the Sixers, season-ending surgery is not yet an option for Richardson.
